"MAIA" is a slotted driveable gutter used for the drainage of motorways and airports. T.S.S. adapted the SATUJO slotted gutter method to be realized on a slipform paver. The new concept is based on the insertion of an air inflated reusable flexible tube on a slipform paver which enables the pouring of the concrete and simultaneously the creation of the slot to drain the water. This method allows for high outputs of about 300-400 rn/day with low costs and an exceptional quality.
